Bus resets while realtime job is running

Hi,
On current kernels (at least 2.6.19 to current -- I can't test older ones),
realtime processes cause USB resets on my system.
I'm running pulseaudio with realtime privileges. This happens:
[23496.395029] usb 6-3.2.1: reset low speed USB device using ehci_hcd and address 42
[23496.937542] usb 6-3.1: reset low speed USB device using ehci_hcd and address 39
[23512.660307] usb 6-3.2.1: reset low speed USB device using ehci_hcd and address 42
[23513.699371] usb 6-3.1: reset low speed USB device using ehci_hcd and address 39
[23531.379236] usb 6-3.2.1: reset low speed USB device using ehci_hcd and address 42
[23553.950417] usb 6-3.2.1: reset low speed USB device using ehci_hcd and address 42
[23565.124676] usb 6-3.2.1: reset low speed USB device using ehci_hcd and address 42
The devices in question happen to be my mouse and keyboard. :-/
Unfortunately the keyboard manages not to survive that reset (it starts
losing events, which is kindof inconvenient when the lost event is a
key-up) and needs to be unplugged to resume working.
I don't have audio (or anything else that's active, in fact) on my USB.
Ideas where to start debugging this are appreciated.

We didn't put in ^^ because then we'd have to keep telling people what
it means, and then we'd have to keep telling them why it doesn't short
circuit. :-/
